Due to people’s increasing demands and expectations, most of the cars manufactured come with standard fitted air conditioners.
The cooling (AC) compressor in your vehicle supplies cold air and power to the cooling framework. This little gadget works by stirring up the pressure as the engine works and moving air into the car.
The air conditioner contains a modest quantity of liquid, which goes about as an oil to keep its parts cool and running smoothly during activity. If the fluid leaks oil out of the air condition compressor, you should fix your vehicle’s cooling control system.
What Causes AC Compressor Oil Leakages?
Inactive Airconditioning System
Numerous individuals ask what support steps they should take for their standard air conditioning framework. Cooling system experts have consistently given the same, direct recommendations, “Use your air conditioner.”
Despite everyday reasoning, the refrigerant is not drained by using your cooling system.
The most notable explanation behind oil loss in a working compressor is at the compressor shaft seal. This is usually the aftereffect of vehicles that are not driven consistently and additionally experience irregular use.
Shaft seal spills have been known to happen with times of inactivity as short as a fortnight. The actual outcome is a potentially shaft seal compressor oil leakage.
How To Fix It
A mostly ordinary secret reality about the air conditioner compressor is that the pole seal is kept greased up the whole time the blower is locked in and running. Numerous industrial facilities’ air conditioning systems lose their charge when the air conditioner is not used.
This occurs as an under-greased up seal around the compressor’s crankshaft evaporates and builds up a release that allows oil leaks. This was not such an extensive issue some years back when you could carry your vehicle to any help station and get R12 emptied into your car.
Clanking Noise From Your Cooling System
Suppose the oil leaks out of your vehicle’s air condition compressor. In that case, you may hear clamors and shaking as the blower runs dry and comes up short on the oil it needs to run efficiently.
Some compressors make more commotion than others. Pay close attention. Suppose your vehicle’s cooling framework starts making thumping clamors or metallic or pounding clamors. In that case, it may result from leaking compressor oil, which has led to a malfunction.
How To Fix It
Have an eye for details to observe if your compressor is leaking oil while in motion or in a static position. Additionally, listen for noise coming from your air conditioning system when turned up to check for noise.
Merely keeping your compressor lubricated will help maintain your air conditioner’s full working capacity and provide you the best air needed for a smooth drive.
Seized Compressor
The air conditioner compressor serves as a passage for both coolant and oil. Consequently, if you experience oil leakage, it may cause your compressor to seize and quit working altogether.
The resultant effect is that your air conditioner will no longer supply cold air into the car. You may hear screeching commotions from the belts as they try to turn the seized-up compressor.
How To Fix It
An Air Conditioner compressor contains a pump. This pump, if it leaks oil, it can seize. The driver can utilize a break locator to decide the hole area and seal it as needs be.
After fixing the leakage, compressor units, accessible at numerous auto parts supply stores at an ostensible expense, contain greasing up oil for an oil change and refrigerant to top up the compressor.
Reestablishing legitimate oil and refrigerant levels in the compressor should free it and reestablish its standard working capacity.
External And Internal Compressor Oil Leakages
Breaks can happen both remotely and inside around your AC compressor. Leakages from the outside naturally occur in the areas around the compressor shaft seal, gaskets, condensers, O-rings evaporators, and connectors.
Check all these areas thoroughly if you think your air conditioner compressor is leaking oil.
Internal leakages can be challenging to identify, so you may need to use a color or an electronic leak finder to pinpoint the leaking areas. You will most likely be unable to recognize internal compressor oil leaks without dismantling the compressor.
How To Fix It
From the start, you need to recognize where the oil is spilling from your compressor. It tends to be from the piston chamber or the oil chamber. It is easy to discover as you will see the oil spill with your unaided eye when it begins to spill.
When you distinguish the spillage, you need to find out why it is spilling from that point. It could because of too much oil added.
After distinguishing the reason and the spillage point, you need to dismantle the compressor. There is no point in disassembling the whole compressor. Merely the area where the leakage has happened.
At this stage, the intention is to repair the leaking spot after you have cleaned it dry. On the off chance that the assembling was not adequate and caused the leak, you would now be able to reassemble firmly. Also, if there was excess oil provided, you need to quit giving a lot of oil.
From Air Filter
The filter serves as an air-channel that cleanses the air before they run into the compressor. The filter has several connections through the pipes. If you keep the lines of the filter loose, the oil will leak from the filter.
How To Fix It
You can either replace the filter, which by the way, is unbelievably cheap or have it dusted and inserted back.
The risk with the latter option is that you will, in a short while, start to experience leakage again and until you change the filter so cleaner air can flow through your air conditioning system.
Too Much Oil In The Chamber
If more oil is in the chamber than expected, the overabundance of oil will spill from the chamber. Additionally, abundant oil noticeable all around the compressor channel will make the oil leak too.
How To Fix It
Where you have too much oil in your air conditioning compressor, you need to drain it for the best result. There is a limit on the quantity of the oil that should be in the compressor at any given time. If you are unaware of this, please refer to the manufacturer’s manual or your auto mechanic.
From The Top Of The Compressor
Somewhere else from where the oil can spill is from the top of the compressor. The oil will spill from that point if the oil cannot appropriately move through the channel or the oil chamber.
How To Fix It
The cleaning aspect incorporates wiping off the oil that poured out of the compressor. It likewise includes cleaning of the pieces of the compressor you dismantled. You must fix the leakage parts after cleaning the oil to see where the fault came from clearly.
On the off chance that any parts have openings or damaged top, you can either fix them or change them. You can use an oil seal to keep spillage from the top. It is more intelligent to change than to replace it with another.
From Piston Chamber
A large portion of the oil you apply goes to the piston. The cylinder should be as greased up as conceivable to make the air compressor run efficiently. Yet, occasionally, if there is an opening anytime on the cylinder chamber, the oil gets spilled from that point.
How To Fix It
From the start, you need to recognize where the oil is spilling from your compressor. It tends to be from the piston chamber or the oil chamber. It is easy to discover as you will see the oil spill with your unaided eye when it begins to spill.
When you distinguish the spillage, you need to discover why it is spilling from that point. It could because of too much oil added.
In Conclusion
A correctly working air conditioner with no compressor problems provides you will some comfort.
- A cool and more relaxed driving experience for the driver and passengers
- A safer drive
- De-misted windscreen
- An aerodynamic atmosphere in your car
All these are possible and achievable if the air conditioning system in your car works perfectly. However, when you struggle with getting cool air, you get warm air in, which is an indication that your car air conditioner compressor is leaking oil.
